So i have a horizontal Bar chart on jaspersoft studio 6.2.0 and i want to fix the Y axis on zero value of X axis(chart has negative values), but no matter what i do it stick always to left side of chart.

It's the labels that are problematic - the code is all written under the assumption that the labels are on the left or right side, never in the middle of the chart. Your client will have to have their "expectations managed"
